EMERGENCY-COT.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed May 17. 1907. Serial No. 374.222.

To all whom it may concern:

Be it known that I, MARTIN H. TnoMrsoN, a citizen of the United States,residing at Schenectady, county of Schenectady, and

State of New York, have invented certain new and useful Improvements inEmergency- Cots, of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described and subseuently claimed.

Reference may e had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several fi res therein.

Figure 1 0 the drawings is a view in side elevation of my improved cotset up for use. Fig. 2 is a top plan view of the same. Fig. 3 is an endview of thefolded cot. Fig. 4 is a vertical cross-section of the sametaken on the broken line 44 in Fig.3. Fi 5 is a view in elevation of oneside of the fol ded cot. Fig. 6 is a similar view of the opposite sideof the cot. Fig. 7 is a side view of oneof the side-bars detached,partly broken awayand partly folded.v

The principal object ofthe invention is to provide a cot or bed adaptedfor use in emergencies, and capable of being knocked down and stored ina small space when not in use or when it is desired to transport thesame from place to place.

Referring to the drawings wherein the invention is shown in preferredform, 1, represents the head and, 2, the foot of the cot,

each comprising a hollow'structure or casing adapted to contain certainother portions of the device and each open on the side toward the otherwhereby said casings are together adapted to form an inclosure.

Theh'ead and foot when not in use are supported upon folding legs, 3,each fitting with in asocketA, on the head or foot, and having its innerend provided with a slot having a rectangular end at, 6, adapted toreceive and closely fit. a rectangular pin or bar, 7, extending throughthe socket, the other end of said slot being enlarged at, 8,'to looselyreceive said rectangular pin. The dimensions of the socket are such thata longitudinal slide-.

vertical or horizontal position.

. in cross-section, the body 1 movement of the leg is permitted ineither a When the cot is in use the legs extend vertically, with therectangular pin, 7, seated in the rectangular portion, 6, of, the-'slot. Each leg can be folded bylifting the head or foot-of the cotwith which it is connected, then forcing the leg outwardly until thepin,7, is located in the enlarged portion, 8, of the slot. The leg isthen swung inwardly to a horizontal position, and in this position isforced outwardly to again seat the pin, 7, in the rectangular portion,6, of the slot which serves to hold the leg in folded horizontalposition.

The head and foot of the cot are connected together by a flexiblebottom, 9, preferably made of canvas, connected at one end with the headat, 10, and connected at its other end with a drum or roller, 12, uponwhich it is ada ted to be wound. The trunnions of the IQ ler, 12, havebearings in the end-walls of the foot, one of said trunnions, 13, havingfixed thereon a ratchet, 14, and means for rotating the same, as ahand-wheel, 15, located exteriorly of the foot at one end thereof. Theratchet, 14, is adapted to be engaged by a spring-actuated dog 16. Thehead and foot of thecot are also connected together by a pair of foldingside-bars, 17, each having hook-ends at 18 adapted to engage recessedportions of the head and foot. One member of each sidebar is ofchanneled form in cross-section and the other T-shaped of the "if-shapedmember being adapted to e within the channeled member when the bar isfolded. The two-bar members are connected together bya rectangular pin,19, inserted through the channeled member and through one end of thebody of the if-shaped member, the latter being stripped of itshead-fiangesadjacent to said end and provided with a slot having itsinner end, 20, rectangular in form to fit said pin, and its outer endenlarged as shown at,

21, to loosely receive said pm.

When the side-bar is removed from the cot the bar members can be pulledin opposite directions until the pin, 19, enters the enlarged end, 21,of the slot whereupon one bar-member can be swung upon the other to foldthe bar. The hollow head of the cot is adapted to' receive both sidebars when folded. When the side bars are in osition they serve toforcibly-hold apart t e head and foot of the cot so that by winding moreor less of the canvas bottom upon the roller 12, any desired degreeoftension-can be imparted to the canvas bottom which is prevented fromunrolling by the engagement of the dog, 16, with the ratchet 14.

When it is desired to knock down or fold the cot, the dog, 16, isdisengaged from the ratchet, 14, to relieve the tension on. the canvasbottom, the side-bars are removed, folded, and placed Within the hollowhead, and the canvas is again wound upon the roller, 12, until the headand foot are drawn closely together,,-as shown in Figs. 6 and 7, inwhichposition they are retained by the en:

gagement of the dog, 16, with the ratchet, 14.

Ifde sired, the canvas bottom may be provided near the head of the cotwith a looseflap, 22, provided with button-holes ada ted to receivestuds, 23, on the outer side 0 the head adapted to support said flap inan inclined position -to form a head-rest, When the cot is folded orpacked up this flap is de tached from the studs and contained within thehollow-head.

- When desired the cot may be provided with a blanket, 24, connected.with and adapted to be wound upon the drum or roller, 25, also locatedin the hollow foot. The trunnions of the blanket-roll have bearings inthe end walls of the foot, one of said trunnions, 27, projecting fromthe end of the foot opposite that from which the canvas-' roll-trunnionprojects, the blanket-roll trunnion, 27, being provided with an oerating hand-wheel, 28, and with a rate et, 29, adapted to beengaged bya sprin -actuated dog 31. When the cot is to be folded the blanket iswound upon the roller 25. The outer end of the blanket is provided; witha corded or beaded edge, 32 ,'of a size adapted to engage the walls ofthe slit, 30, to revent the complete withdrawal of the lanket within thefoot-casing. When desired the blanket and blanket-roll may be omitted.

My improved cot is adapted to be folded into a small compact packageadapted to be carried in a trunk, if desired, and when needed it can beeasily and quickly set up and made ready for use.

Either or both of the head and foot-casings may be provided withhand-holes, 36, for convenience in lifting or transporting the cot, asshown inFig. 3, or with handles, 35, as shown in Figs. 1 and 2.

What I claim as new and desire to secure by Letters Patent is 1. In acot or bed, the combination with a head-member and a foot-member eachhollow and open on the side toward the other, and together adapted toform aninclosure;

of detachable side-bars adapted to connect together and hold apart'saidhead and footmembers; a flexible bottom connected at one end with one ofsaid head and footmembers; and a roll mounted upon the other of saidhead and foot-members, and connected. with the other end ofsaid flexiblebottom, which bottom enters both hollow members through the open sidesthereof.
